Through Hole Resistors

Through hole resistors, also known as through-mounted resistors, are passive electrical components that limit, direct, or otherwise modify the flow of electric current within other circuitry. Different adjustments in resistance can be made to resistors, and these components are designed in various sizes and shapes depending on the application.

The RSF200JB-73-51R is one of the most common through hole resistors used in electrical and electronic circuits. This resistor, developed by the Vishay Dale Electronics company, features a low-profile through-hole package that can be easily mounted to printed circuit boards. It is made up of a standard 0.125” × 0.125” (3.2mm × 3.2mm) horizontal perforated ceramic body, an iron-based resistive element, and a flame-retardant epoxy coating. As a result, it offers a high level of flame-retardance and is certified to UL94V-0 standards.

In most applications, the RSF200JB-73-51R operates as a fixed value resistor, for example, as a power-lines noise filter or a voltage-divider. When used in such scenarios, the internal resistance element determines the maximum amount of electrical current allowed to pass through the circuit, thus protecting it from overvoltage or short-circuit damage. Additionally, the standard ceramic composition and design of the component allows it to dissipate heat more efficiently, preventing potential damage due to high temperatures.

The RSF200JB-73-51R is also used in more complicated circuits that require adjustments in resistance. It can be used in circuits with adjustable resistance elements, which allow the device to adapt to changing environmental conditions. Such adjustable resistors are found in thermocouples, strain gauges, bridge circuits, and other measuring devices. In these circuits, the component’s resistance can be fine-tuned to achieve desired results. As an example, the component can be used in a bridge circuit to measure pressure by adjusting the resistance to calibrate the signal sent to the device.

Finally, the RSF200JB-73-51R is also used in optocouplers to isolate two circuits of different voltage and current levels. In these types of applications, the internal resistance element and epoxy coating help keep heat dissipation low while also allowing higher voltage to pass through the component.

The RSF200JB-73-51R is an exceptionally versatile component commonly found in electrical and electronic devices. It can be used in various applications, from power-line noise filters and voltage-dividers to adjustable resistors and optocouplers. Thanks to its high levels of flame-retardance and ability to dissipate heat more efficiently, the RSF200JB-73-51R is a reliable and versatile choice for electrical and electronic circuit designs.
